Evidence suggests that people evaluate outcomes relative to expectations. I analyze this expectation-based loss aversion (Köszegi and Rabin (2006, 2009)) in the context of dynamic and static auctions, where the reference point is given by the (endogenous) equilibrium outcome. If agents update...

When goods are substitutes, the Vickrey outcome is in the core and yields competitive seller revenue. In contrast, with complements, the Vickrey outcome is efficient but not necessarily in the core and revenue can be low. Non-core outcomes may be perceived as unfair since there are bidders...

In an experiment we first elicit the distributional preferences of subjects and then let them bid for a lottery, either in a Becker-DeGroot-Marschak (BDM) mechanism or a Vickrey auction (VA). Standard theory predicts that altruistic subjects underbid in the VA - compared to the BDM - while...

This paper studies collusion in one-shot auctions, where a buyer can bribe his competitors into lowering their bids. We modify the single-unit Vickrey auction to incite deviations from the designated-winner scenario and thus undermine collusion. The construction of mechanism does not require the...

Conformity behavior, i.e. the agreement between an individual's choices and the prevailing behavior of a reference group, is a commonly observed phenomenon. Though some types of social interactions may give raise to specific incentives to adopt either a majoritarian or a contrarian behavior, we...

Eliciting sincere preferences for non-market goods remain a challenge due to the discrepency between hypothetical and real behavior and false zeros. The gap arises because people either overstate hypothetical values or understate real commitments or a combination of both. Herein we examine...

It is common practice to have subjects make decisions which pay out in a fictitious experimental currency. Earnings in the experimental currency are then converted to cash at the end of the experiment. Like many practices in experimental economics, however, these procedural choices seems to be...

This article contributes to the research agenda of accommodating psychological insights in conventional lab experiments. We specifically test whether inducing subjects into different mood states has a significant effect on subjectsâ€™ rationality (in the form of preference reversals) and on...

We use the Vickrey–Clarke–Groves auction mechanism to propose a system of primary auctions of slots at congested European airports. The system would ensure allocative efficiency and would be incentive-compatible, flexible, understandable, implementable and transparent. Only 10% of slots...

We develop a framework for the optimal bundling problem of a multiproduct monopolist, who provides goods to consumers with private valuations that are random draws from a distribution with heavy tails. We show that in the Vickrey auction setting, the buyers prefer separate provision of the goods...

This paper explores how the initial farm size structure affects the exit decision of farms inducing free land capacities, and the allocation of the newly available land resources to the remaining farms in a particular region. We model an agricultural market where large and small firms first...

We consider a dynamic auction environment with a long-lived seller and short-lived buyers mediated by a third party. A mediator has incomplete information about traders' values and selects an auction mechanism to maximize her expected revenue. We characterize mediator-optimal mechanisms and show...

Eliciting sincere preferences for non-market goods remains a challenge due to hypothetical bias - the so-called gap between hypothetical monetary values and real economic commitments. The gap arises because people either overstate hypothetical values or understate real commitments or a...

We analyze a model of Internet auctions. Sellers each offer one item of a heterogeneous good to bidders who have unit-demand preferences. Items are sold in second-price proxy auctions. We derive a perfect Bayesian (epsilon-) equilibrium. Our experimental findings support the theoretical results....

When goods are substitutes, the Vickrey auction produces efficient, core outcomes that yield competitive seller revenues. In contrast, with complements, the Vickrey outcome, while efficient, is not necessarily in the core and revenue can be very low. Non-core outcomes may be perceived as unfair...

We propose a new, easy-to-implement, class of payment rules, “Reference Rules,” to make core-selecting package auctions more robust. Small, almost riskless, profitable deviations from “truthful bidding” are often easy for bidders to find under currently-used payment rules. Reference...

This paper investigates the coordination mechanism for supply chain with one manufacturer and multiple competing suppliers in the electronic market. We first study two conventional price-only policies, including wholesale price policy and catalog policy, based on the reverse Vickrey auction, and...

For economies in which goods are available in several (discrete) units, this paper identifies two notions of substitutes. The weaker notion guarantees monotonicity of tatonnement processses and convergence of clock auctions to a pseudo-equilibrium, but only the stronger notion, which treats each...

We introduce a subsidized Vickrey auction for cost sharing problems. Although the average, marginal, and serial cost sharing mechanisms are budget-balanced, they are not allocatively efficient and they do not induce players to truthfully reveal their values as a dominant strategy. The...

This paper completely characterizes the set of Nash equilibria of the Vickrey auction for multiple identical units when buyers have non-increasing marginal valuations and there at least three potential buyers. There are two types of equilibria: In the first class of equilibria there are positive...

This note provides a simple explanation why sellers rarely set optimal reserve prices in one-shot auctions. In a standard sealed-bid second-price auction, bidders with private values do not bid truthfully if the seller cannot commit to her announced reserve price. Consequently, expected revenue...

This paper studies endogenous entry and ex ante revenue-maximizing auctions in an independent private value setting where potential bidders have private-information entry costs. The contribution of this paper is four-fold. First, we show that any equilibrium entry can be characterized through a...
